请先通读下列短文，然后从所给的七个选项中选出能填入空格的最佳选项。
1_____ One of the best things you can possibly do is to start you own club. It's great fun especially if you
are the sort of person who feels there's never anything to do during the school holidays.
The first thing you need to come up with is an idea for your club. What are you interested in? Pets, clothes,
pop music or dancing groups, sports, or making things? 2_____
Next you need some friends to be in your club with you. 3_____ All you need is three or four other people
who are interested in the same thing as you.
4_____ You should all sit down somewhere together with lots of pieces of paper and write down every name
you can think up. That'll keep you busy for ages.
At your first meeting you should make up a rule book. And the first rule should be no grown-ups or little/big
brothers or sisters! The best clubs are always secret!
Now you have just about everything you need, except membership cards. These are very important and again
you will spend a lot of time making them. Use a bright thick pen to make a special design. Why not leave some
space for a photo of yourself? 5_____
So there you are, get clubbing! Once you get started you'll think of loads of more interesting things to do!
A. That's easy.

C. Enjoy your own club!
D. Invite a designer to join you.
E. Winter vacation is just around the corner.
